- debian/control add sisu-pdf texlive deps, primarily cjk related
- debian/control sisu git
- debian/compat bumped up
- debian/watch removed, source only upload

SiSU 7.3.0

- ctex preferable to xeCJK? (if/when it works)
- note: the current round of texpdf changes relate
  to a bug report on the old live-manual
  for debian-live to wit:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1052693
- apparently sisu-pdf does not produce latex
  suitable for the latest texlive (texlive-2023)
- some of the latex output changes here are from
  sisu:spine, the dlang version of sisu

- font rendition bugs where tested

- reported on debian in relation to live-manual
- make use of latex output for sisu.spine.d
  - was developed more recently, a comprehensive
    output update with focus on utf-8 improvements
    available in more recent version of texlive
  - tested forward does not appear to be
    similarly affected
  - other issues likely to appear as no attempt is
    made to fully backport the output for spine.d
    to sisu.rb
